So, in MCQ mode, we are re-directing all zoned writes to one HW queue
to preserve the write order, is my understanding correct?
That's somewhat but not entirely correct. As one can see in patch 20/26,
the software queue (and hence also the hardware queue) that was selected
for zoned writes is unselected after all pending zoned writes for a
given zone have completed:
+ if (refcount_read(&zwplug->ref) == 2)
+ zwplug->swq_cpu = -1;
So the next time a write bio or write request is submitted a different
queue may be selected.
Understood, thanks for explaining.
